PROFILE
Berk Cem Goksel
Over a two-month period, contributed to the torvalds/linux and google/syzkaller repositories by enhancing USB audio and MIDI driver reliability, expanding fuzz testing, and improving cross-architecture compatibility. Focused on C and Go programming, the work included safe cleanup of ALSA USB audio mixer controls to prevent use-after-free crashes and broadening Syzkaller’s fuzzing coverage for USB audio classes. Addressed regressions in USB descriptor handling, strengthened driver initialization, and refactored code for maintainability. These efforts improved hardware compatibility, stability, and testing reliability for USB audio paths, demonstrating depth in Linux kernel development, device driver engineering, and system-level testing methodologies.
